Repair or buy another car?

What is your question?

My 2012 Juke is burning oil w/ excessive oil found in the turbocharger intercooler pipes/ turbocharger is worn. Also valve cover gasket is leaking internally. Just did tune up. 92 k miles . Is it worth the $3500 in repairs or time to find a low mileage Toyota? Fear is spending $4000 and then engine goes out. Thx
